Samsung blamed faulty batteries and began to issue replacement handsets, which it claimed were completely safe.

However last week a flight in the US was evacuated before it could take off when one of the newer models began to emit smoke.

In America, mobile carriers AT&T and T-Mobile said they would no longer replace Note 7s while T-Mobile added on its website: "While Samsung investigates multiple reports of issues, T-Mobile is temporarily suspending all sales of the new Note 7."

Samsung stated on Monday: "We continue to move quickly to investigate the reported case to determine the cause and will share findings as soon as possible.

"If we conclude a product safety issue exists, we will work with the CPSC (US Consumer Product Safety Commission) to take immediate steps to address the situation."
